Mine are the more common ones. Big Pokemon, Zelda, Rhythm Heaven and Animal Crossing fan. I've recently also got into the Fire Emblem and Kirby series. I'm also partial to a bit of Mario and Donkey Kong. I'm also going to count Okami as a franchise because there's two games.

I would say Pokemon takes my #1 spot. It's certainly my most purchased-from franchise. xD Mario would be second on the money list, but just because there are so many games. >: I'll buy them and want to beat them, but they're not really my favorites. Then on Xbox, there are so many different games that are really fun, but so many different series to choose from!

I've played 4, but I guess Star Fox 64 and Star Fox 64 3D probably count as the same ones. XD

Star Fox Assault and Star Fox Adventures were pretty awesome though Tbh Adventures was probably my favorite though, I liked the change of pace. x3 plus the main character is a fox and that's just plain awesome

From Nintendo, my favorites have to be Mario, Metroid, and Star Fox.From Sony, it's the Uncharted Series as well as Jak and Daxter.

Outside of the big 3 companies(Nintendo, Sony, Microsoft), I also have to say Rayman from Ubisoft. I absolutely love the N64 and Playstation Rayman games.Also, Rayman Origins is by far the best platformer of this generation.
